MEANS FOR TRIMMING BURS FROM THE CUT ENDS 0F PRINTERS RULES.

Specification of Letters Patent.

Patented May 7, 1912.

Application led February 10, 1908. Serial No. 415,126.

To all whom it may concern: v

Be it known that I, CHARLES F. REMING- TON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Means for Trimming Burs from the Cut Ends of Printers Rules, of which the following is a full, clear, and eXact specification.

This invention relates to improvements in means for trimming burs from the cut ends of printers rules, which trimming has heretofore been confined to a manual operation, consisting in rubbing the rule against a cutting surface, consisting of emery or sandpaper or other gritty substance while holding the rules in the hand, and which at best is unsatisfactory for the purposes of perfect rules, because o-f the diliiculty in determining how hard and how long to rub them in order to cut away the rough edges, i. e., the bur produced by and necessarily following the sawing of metal and particularly brass rules in lengths. v

The prime-object of my invention is to remove the bur from sawed printers rules by an operation entirely mechanical, and by the employment of metal-cutting blades, and in so doing remove the bur without substantially or perceptibly removing any of the body portion of the rule.

A further object of my invention is to provide means by which printers rules, varying in length, are automatically fed past the vtrimming devices, and discharged from guides directing them in their movements past the cutters, and to simultaneously trim both ends of a rule.

Another object of my invention is to provide means whereby the guiding devices for the rules in their passage past the cutters may be accurately and with certainty adjusted to rules of any thickness.

A further object of my invention is to conduct the rules past the cutters by a force uniformly applied against and throughout j Vthe length of an edge of the rule, and thereby prevent any possibility of the rules wedging in their guide.

A still further object of my invention is to mechanically trim the burs from sawed ends of rules by a mechanical structure, the driv- -ing shaft of which may be actuated either tain other objects hereinafter appearing are.

attained, all as fully described with reference `to the accompanying drawings, and more particularly pointed out in t-he claims. In said drawings: Figure 1 represents a top plan view ofI a rule-trimming machine embodying my'invention. Fig. 2, a rear side elevation thereof.

-Similar `characters of reference indicate the same parts in the several figures of the drawing.-

18 is an approximately rectangular bedplate supported at its corners by legs, 19, having lateral flanges, 20, provided with suitable openings, 2l, whereby the bed-plates may be secured to a suitable bench or support.

Depending from one end of the bed-plate are brackets, 22 and 23, in which is ournaled the power-shaft, 24, of the machine, having on its outer end a hand crank-wheel, 25, but which may be a belt-wheel connected with some suitable source of power not shown.

On the inner end of the power-shaft, 24, is a crank-wheel, 26, to which is pivoted at one end a link, 27, the other end of which is pivoted to a post, 28, projected upwardly through a slot, 29, in the bed-plate, and screwed into a feed-bar, the stem, 30, and cross-head, 31, of which are countersunk in the bed-plate, and the cross-head connected with the stem (see Fig. 4) by recessing it therein, and at which point the cross-head is provided longitudinally with a groove, 32, (see Fig. 5) for the lateral adjustment of the push-er bars, 32a-32a, hereinafter described, simultaneously to cutter-bars for rules varying in length.

In a plane between the power-shaft and the bed-plate is a shaft, 32", journaled at its free end in a hanger, 33, and projecting through the legs of the machine, is journaled at its outer end in a boX, 34, and provided with a crank-wheel, 35, for its operation.

The shaft, 32h, is provided toward its opposite ends with right and left-hand screw-threads, 36 and 37, working respectively in nuts, 38 and 39, having stems, 40- 40, projecting through bed-plate openings, 41-41, respectively secured to opposing cutter-bars, 42 and 43, by means of screws, 44-44, passing through the cutter-bars into their respective stein-nuts, and whereby the cutter-bars are moved toward and away from each other, said bars being guided in their movement by plates, 45, screwed to the bedplate and projecting over the side edges of the cutter-bars, the length of the elongated slots, 41-41, in the sbed-plate determining the length of movement of the cutter-bars, and lateral adjustment of the rule-holding and cutting devices.

Secured by means of ordinary set-screws to the opposing inner ends of the cutter-bars are (see Fig. 11) plates 46 and 47, and formed in the plate 47 and the cutter-bars is a recess, 48, in which is confined under cutters, 49, 49, the cutting edges of which extend at an oblique angle to the length of the cutter-bars and therefore likewise to the length of the rules to be cut, the shanks of said cutters (see Fig. 12) being provided with a slot 50, in which project the iianges, 5l, 51, of adjusting screws, 52, 52, the raising and lowering of which flanged screws regulate the vertical adjustment of the respective cutters and plates 46 and 47, the screw 52 being counter-sunk in the bed-plate sufficiently to maintain the head of the screw below the plane of the bed-plate when adjusted to the limit of its upward movement and from contact with the upper cutterheads, presently to be described, the cutting blades being locked in their adjustment by a set-screw, 53, (see Figs. -10 and l1) projected through the plate, 46.

Secured to and rising from each sliding cutter-bar are posts, 54-54, the upper ends of which posts are screw-threaded for thumb-nuts, 55-55, impinging against the upper ends of tubes, 56-56, sleeved upon the posts (as indicated by dotted lines in Fig. 9) and having an end bearing down against opposing upper cutter-heads, 57, respectively resting upon the opposing cutterbars, the cutter-heads being provided with perforations whereby they are removably secured by the posts against movement in any direction and held rigidly upon the cutterbars, as above described.

The upper cutter-heads are provided with cutters, 58, similar in construct-ion and arrangement to the lower cutters, and like the lower cutters are adjusted vertically by means of flanged screws, 59, projected in the slots of their shanks, which screw however need not be countersunk below the upper surface of their respective heads, for the reason that there is no surface opposing` it, and these upper cutters are also locked in their vertical adjustment by a set-screw, 60, (see Fig. 10) in the same manner as the lower cutter-heads. Toward their forward ends the upper cutter-heads are provided with an angular recess, in which, and rising above the plane of the cutter-heads, are corresponding angular plates, 61, in which may be stacked a number of rules, 62, (see Fig. 9) and with the result that they may be automatically consecutively fed by gravity in position to be carried past the cutters by the feed-bar. The upper cutter-head also sustains a stop, 62a, (see Fig. 9) the shank, 63, of which is angular in cross-section and confined by a corresponding perforation in the cutter-head in which it is free to slide vertically, the stop being norn'lally projected below the plane of the bottom of the cutter-head by means of a spring, G4, (see Figs. 6 and 9) one end of which is clamped to the cutter-head by a screw, 65, and the other end projected through a perforation in the shank, 63, the stop, 62, (see Fig. 9) being rounded on its front side and with an angular face at its rear side, so that when a rule is pushed past the stop it will immediately yield and rise to the pressure of the rule, but the moment the rule passes beyond its straight edge will descend to the position shown in Fig. 9, and prevent the movement in a reverse direction through its impingement against the straight side of the stop, the vertical movement of the stop being sulicient to adapt it for rules varying substantially in thickness.

The undersides of both cutter-bars are grooved (see Figs. 7 and 10) to a depth corresponding with the thickness of a slide-bar, (i6-66, confined in their respective grooves by plates, 67-67, secured to the cutter-bars and projecting over the edges of the slidebars, 66, upon the underside of which slide bars are secured, by-one or more set-screws, 68, lugs, 69, 69, having respectively formed therewith brackets, 70, 70, projecting beyond the eXtreme opposing ends of the cutterbars, to which brackets are secured the feedbars, 32, by means of set-screws, 7l, (see Fig. ll) cut away to form shoulders, 72, 72, (see Figs. 5 and ll) adapted to engage the edges of the rules, and by the' forward movement of the feed bars, push the rules past the cutters.

Bolted to the under and outer edge of the frame of the machine, (see Figs. 2, 4 and 5), by bolts 73, 78, is an apron 74, provided with opposing side flanges 75, 75, through which the bolts pass into the frame, the outer end of the frame being open, and its inner end closed by a flange 76 projecting upwardly against the edge of t-he bed plate 18, said frame providing a support for a removable rule receiving pan 78 inclined downwardly from its outer toward its inner end supported by flanges or legs 77 resting on the apron 74 from the inner end of which pan 78 projects a flange 79 against the edge of the bed plate, 18, and in close proximity to the flange 76 of the apron 74. The incline of said flange 79 and of the plate 78 is such, that the trimmed rules discharged from their pusher bars 32a will pile one upon the other in numbers forming stacks of substantial height, yet so stacked as not to topple over when removing the pan from the machine and the stacks from the pan to a table and thereby effect a substantial saving in time in handling and packing for shipment the printed rules.

ln operation, when a number' of rules of the same length are to be trimmed one of such rules is placed upon the pusher bars and then by manipulating the hand wheel 35, the sliding cutter bars 43 are moved toward each other until against the opposite ends of the rule, but not too tightly to prevent free passage of the rules to operative engagement with the cutters.

After the machine is thus properly adj usted to the length of the rule to be trimmed the thumb nuts 55 and tubes 56 are removed from the standards 54 and of the 'same length and also thickness and a pattern rule 80, (see Fig. 15), of the same length and also thickness is then slipped upon the edge of the standards 54, 54 by means of perforations 8l, 8l therein for that purpose, after which the tubes 56 are returned to their operative position and the nuts 55 tightened thereon until. the pattern rule is firmly clamped between the bed plate and the sliding cutter bars, and the cutters thereby adjusted for subsequently trimming the 'rules to uniform thickness.

lf other rules of the same length either thinner or thicker than those for which the machine has now been fully adjusted are to be trimmed it is then only necessary to relmove the pattern rule 8O and substitute one to correspond in thickness. After the machine has thus been properly adjusted to length and thickness of the rules to be trimmed they are piled in their' guides or chutes, as shown in Figs. 3, 4 and 9, in such a posit-ion that on actuating the shaft 24 the pusher bars 2a will push one rule at a time in operative engagement with and past the cutters, which rule in the withdrawing of the pusher bars to the normal position is prevented from following it by the stop 6, and as the pusher bars recede.. drops into the removable pan wherein the successively -discharged rules pile in such a manner as `to touch against the flange 79 of the pan and against the-)toppling forwardly over from their piled position.

By the time the presser bars have moved to the limit of their backward stroke their rollers 72 have passed clear of the bed plate of the rules the resultbeing that by gravity the adjacent rule drops upon the feed bar in position to be fed forwardly past the cutters as already described and thereby the piled rule is successively trimmed on both edges at each downward stroke of the pusher bars, and in any bars that may be placed in the feed chutes for the rules.

In the practical operation of the machine herein shown and described as the mechanical embodiment of my invention many thousand rules may not only be trimmed of their burs simultaneously at both ends in the course of a few hours, and the burs are not only quickly and entirely removed from the rules, but this without cutting into the body thereof, and whereby the ends of the rules are not reduced in thickness nor even visibly marred. On the other hand, when the common practice is followed of rubbing the rule with or against emery paper it is practically impossible to entirely remove the burs without scratching or otherwise defacing the surface of the rules to a considerable distance inwardly from both cut ends, and therefore beveling the surface of rules more or less adjacent their lower edge, and to a degree rendering them objectionably inaccurate in use. Again when at best the bur is removed from the surfaces of the rule by present hand manipulation there will still be burs -projecting from the ends of the rules, prevented by my invention for the reason that the ends of the rules s0 closely lit between the ends of the sliding cutter bars that none of the bars can be bent downwardly over these ends or out of the path of the cutters, for when a proper adjustment, easily and quickly made, of the sliding cutter bars, it is impossible for any of the burs to escape removal by the cutters, and this without any liability to mar the rules.

In Fig. 16 is illustrated as nearly as may be an untrimmed rule, z'. e. a course set rule with the burs still adhering thereto, and in Fig. 17 is the same rule after it is trimmed, and in which every surface including its edges are perfectly smooth, the corners of the under edges being as smooth as the previously nished side edges.

While the oblique arrangement of the cutter knives relative `to the path of movement of the rule is preferable for the purposes of a shear and smooth c ut of the burs from the rule as is possible, my invention includes any other arrangement of the cutters by which it is possible to remove the burs without seriously injuring or marring a printers rule.

My invention is therefore not limited to any particular form or direction of movement the cutter may have relative to the rules to be operated upon, nor is it limited to the special form of the pusher bars, the means for actuating them, the form and operation of the stop, for my invention includes any mechanically actuated means by which rules may be fed to and. past cutters operating to remove the burs therefrom without defacing or otherwise injuring the rule; nor is it limited to any other details of construction, in view of the fact that I am not aware of any machine for trimming burs off printers cut rules, or which is adapted to entirely remove burs from cut ends, in the absence of hand manipulating operation, or by abrasion, as distinguished from cutting knives.
